Time domain analysis of switching transient fields in high voltage substations [PDF]
, 2009 Switching operations of circuit breakers and disconnect switches generate transient currents propagating along the substation busbars. At the moment of switching, the busbars temporarily acts as antennae radiating transient electromagnetic fields within ...

SF6 Emissions from a National Population of High-Voltage Switchgear [PDF]
, 2023 Twenty years of careful recordings of SF6 inventories and emissions from a large switch-gear population show that by implementing appropriate measures, annual emission rates as low as 0.2% can be achieved.

High Voltage, Volume 11, Issue 1, Page 192-200, February 2026.ABSTRACT Surface discharge is a typical fault type in electric power equipment. High temperature in long‐term operation can easily lead to ageing of materials, resulting in changes in surface characteristics and surface discharge faults. In this paper, a method of surface discharge identification of silicon rubber (SiR) based on spectral detection ...

Power Line Communication as a Sensor: Medium Voltage Cable Diagnostics
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This article investigates the use of broadband power line (BPL) communication as a diagnostic tool for medium‐voltage cables. Experimental results show that BPL modem parameters change in the presence of partial discharges, enabling real‐time monitoring of insulation health and supporting predictive maintenance.
